The equations describing the movement of the trunnion points of the ball mill are derived. The stressstrain state of the trunnion of the ball mill was determined depending on the temperature of the inner and outer surfaces of the trunnion. Deformations and stresses arising on the surface of a pin are investigated by numerical methods.
